理论联系实际的原则是物理教学必须认真贯彻的。多年来,笔者主动收集有关安全生产方面的事例,适当的插入物理教学之中,起到良好的作用。有关的事例不单是有趣味性;而且有针对性、现实性,可作为课题提出,又可作为例题,或课堂讨论等使用。本文只想起抛砖引玉的作用。 1 保持车距市内交通车上经常看到车后面的玻璃上贴有“保持车距”的字样,运行中的车辆有一定的速度和动能,在行车中会遇到各种特殊的原因需要减速或停车,保
The principle of combining theory with practice is that physics teaching must be carried out conscientiously. Over the years, the author took the initiative to collect examples of safety production and properly inserted physics teachings to play a good role. The relevant examples are not only interesting but also targeted and realistic. They can be presented as topics, and can also be used as examples or in class discussions. This article only reminds me of the role of jade. 1 Keep the distance from the car in the city’s traffic vehicles often see the word “keep the distance” on the glass behind the car. The running vehicle has a certain speed and kinetic energy, and it will meet various special reasons in driving. Slow down or park, keep
